摘　　要：在分析了目前现有远程教育技术规范特点的基础上,提出了一种开放式内容对象的组件模型,该组件模型能给可共享Web学习内容的结构与顺序设计提供一种更为灵活高效的方法。首先将学习内容的组成单元设计成具有请求服务与提供服务功能的开放式内容对象OCO,使内容组件不仅可以通过聚集组合成更高级的教学单元,还可以在学习过程中通过以学习管理系统作为中转的消息传递机制形成可互操作的关联关系。最后,通过对ADL的SCORM规范运行环境的扩充,为开放式内容对象OCO在不同的学习管理系统间的运行设计了一个通用运行环境。On the basis of analyzing the characteristics of the current distance education technology specifications, a components model of open content object was put forward that can provide a more flexible and effective method for the design of the interoperable structure and sequence of web-based learning content. In this model, the learning content components were designed to be open content object that had the function of requesting services and providing services by messages transferred mechanism, thus the content components can not only be aggregated to compose higher-level units of instruction, but also can form the interoperable associational relationship by the messages transferred mechanism which takes the learning management system as the scheduling center of messages. Finally, acommon run-time environment for open content object running between different learning management systems was designed by extending the run- Time environment of the sharable content object reference model （SCORM）.
